Ask Rose. Has anyone tried this , its a repeated ad telling you that you might be due money from way back if you received family allowance. I'm now being tempted but they ask all your ID details is it a scam ? Surely DWP would automatically send us all a rebate or form or something ?
Definitely sounds like a scam , DWP would write to you if this was genuine
This could relate to the fact that receiving Child Benefit can count towards your National Insurance contributions if you were a stay at home parent, so affect your state pension. I’m guessing that might be what these ads refer to, though any queries should be taken up with HMRC ( not DWP)
The DWP does not appear to routinely write to everyone to tell them that their Child Benefit has earned them National Insurance credits. The government does provide information about this, but many people may not realise that the credits count towards their State Pension. 
There is one important distinction: Child Benefit is administered by HMRC, not the DWP, although the credits help determine your State Pension.
If you were at home looking after your children and not working, you may have received these credits automatically if you claimed Child Benefit.
